Abstract Scope |
Repairing and depositing of functional edges and surfaces of forming tools can be efficiently performed by additive production using Directed Energy Deposition (DED). DED can be used to deposit directly on the tool and then mill it to the required quality. This paper focuses on tools for trimming membranes and flashes after closed die forging. Nickel alloys such as Nimonic 80A are suitable for these applications, but their price is higher than steel, so it is advisable to apply this material in a small volume to the cutting edge. The research focused on the characterization of the powder, tuning of depositing parameters, and measurement of mechanical properties using miniaturized test specimens. Furthermore, metallographic analysis and hardness measurements were performed. The trimming process was simulated using FE analysis in order to optimize the size of the trimming edge. At the same time, life tests were performed in an industrial application. |
